The scope of this Nordtest method is to determine the sensed draught (combination of local air velocity and low air temperature) created by incoming air through vents for direct supply of outdoor air into a room.

A method of linear calibration of axial load fatigue testing machines is proposed. It is built on the understanding obtained from a vibration analysis of the force transfer function from the load cell of the machine to a fabricated calibration bar. The results have been successfully verified on a commercial testing machine installed at SP in Borås.

An important step in moving toward international standardization is to come to a consensus about what exactly is proper and adequate function in a negative-pressure isolation room. In this report we examine current and best practice in design and performance testing of negative pressure isolation rooms in Nordic hospitals.

Sustainable development requires an environmentally sound, cost effective and socially acceptable management of municipal and industrial waste. Landfilling of untreated municipal solid waste (MSW) is known to lead to emissions of leachate and landfill gas, above all methane, which contributes to the greenhouse effect.

In the EU landfill directive the assessment of waste suitability on disposal is divided into three levels according to intended use. The lowest level, called on-site verification usually takes place on the landfill site and is mainly for control purposes to confirm that the waste quality meets characteristics defined in the two upper acceptability assessment phases.

Between 1987 and 1993 in the U.S.A., the Strategic Highway Research Program (SHRP) surveyed all aspects of the physical tests currently carried out on bitumen, and it was shown that new performance-based methods, such as Dynamic Shear Rheometer (DSR), Bending Beam Rheometer (BBR) and Pressure Ageing Vessel (PAV), are needed.

This Nordtest Project critically examines the deviations from the IMO resolution A.653 (16) method, which the participating laboratories either uses or has been using, that being deviations from: the equipment, the procedures or the interpretation of data. These deviations are in many cases a result on the imprecise and equivocal description of the method described in the IMO resolution A.653 (16) in FTP Code.

In the report the various classes and sub-categories of landfills that are possible within the framework of the EU Landfill Directive are presented and discussed, and the need within the Nordic countries for sub-categories of the three main classes of landfills (inert, non-hazardous and hazardous waste landfills) is evaluated.

An intercomparison has been carried out between 3 laboratories concerning a type test for joints according to EN489 District heating pipes – Pre-insulated bonded pipe systems for directly buried hot water networks - Joint assembly for steel service pipes, polyurethane thermal insulation and outer casing of polyethylene.

Costly certified and commercial reference materials can often not be applied for waste testing because of high test portion quantities needed and poor availability of suitable commercial soil and waste materials. The utilisation of a laboratory reference material can be regarded as a practical tool in the quality control of leaching test performance.

In the SBI fire test, there are temperature sensors in the exhaust duct allowing measurement of the temperature rise of the exhaust gases (T measurement). In principle these sensors provide means to monitor the production rate of thermal energy.

The test method comprises two independent parts, a low temperature phase test and a high temperature phase test. If a construction is to be evaluated according to either part, the two temperature phases may be combined into one test.

This test method specifies a procedure for determining the spontaneous ignition temperature Tc of samples of radius r, and, from these temperatures, the material parameters M and P from the equation where dc is a Frank-Kamenetskii critical parameter.

This NORDTEST method describes procedures for calibration of voltmeters and ammeters which are to be used for measurements of voltage and current during direct current are welding. It also describes test procedures to verify the fitness of an instrument for measurements during direct current arc welding.
